The Problem with PDUs
Using PDUs can result in an unmanageable snarl of cables. Pictured are whips running from a PDU to an
overhead cable tray.
The traditional power-distribution model is to use Power Distribution Units (PDUs) located on the
datacenter floor. These units are usually “breaker panels in a box” from the UPS with individually sized
cables (‘whips’), or hard-wired connections in wireways routed to smaller PDUs in the racks either
overhead or under a raised floor (Figure 12). In some cases they may transform the higher UPS voltage
to lower voltages used by the IT equipment.
equipment There are several disadvantages to this approach that
affect how easily and rapidly a datacenter can accommodate change:
•Adding or changing whips means changing circuit breakers, which opens and exposes
internal components of the PDU, increasing the risk to any equipment to which the PDU
supplies power. This increases the risk of unexpected down time and not compliant with
NFPA 70E.
•“Home runs” of cable for each rack wastes copper.
•PDUs typically have limited circuit breaker positions. As datacenters change, availability of available
breaker positions can become a problem.
•The risk and hassle of removing an unused whip from overhead cable trays or from beneath raised
floors is so great that often cables are abandoned in place. In traditional raised floor datacenter designs
where air is being supplied from underneath the floor, these runs can lead to cooling inefficiency
because abandoned whips create additional obstructions in the raised floor plenum.•

valuable datacenter floor space.

THE ROLE OF MODULARITY IN
DATACENTER DESIGN
The Starline busway is a vast improvement over PDUs for the
following reasons:
•Adding or relocating CB units takes only minutes!
•Power reconfiguration is non-disruptive: circuit breaker plug-in units can
be added, removed, or relocated while the busway is fully energized.
•Shorter copper runs save copper use by approximately 15 percent on
initial install.
•Cables never need to be abandoned in place.
•Future copper needs are also significantly reduced due to the ability to reuse, or re-deploy. busway plug-in units to different locations rather than
adding dedicated circuits.
•The busway supports all densities
densities, high & low,
low as well as increased power
density over time.
•The cost of installing traditional power distribution versus busway to highdensity equipment has become equal. • The busway requires no datacenter
